Research And Implementation Of The Single Board Computer Software Platform Based On SEP3203 Microprocessor

With the rapid development of digital products, embedded software has been applied more and more domains , and its function formidable with more complex. Single Board Computers (SBC) has complete PC's functions and standard periphery interface, and it has traits of constructing embedded system product conveniently and abridging periods of design and research. . With embedded product market becomes speedily mushroom, SBC with advantages of compact, lower power, high performance, will become more and more important and more popular.The platform used in research work is GE01MBT(V2.1) hardware platform which is a SBC. This platform uses SEP3203 micro-processor as core, links periphery circuit module by bus manner and by I/O manner. The works of this thesis is mainly implement software platform based on the SBC's hardware platform, the main tasks include: PS/2 hardware interface module , UART hardware interface module and VGA hardware interface module driver development, replant Operating SystemμC/OS-II, replantμC/GUI and application layer and develop upper application software to achieve call lower driver such as PS/2 driver UART driver and VGA driver.All the works described in the thesi??ve been finished now and succeeded in realization running program on the SBC develope platform.The program controlled by mouse, and running stably.GE01MBT(V2.1) hardware platform has achieved the basic graphic user interactive function and has the basic function of the PC,and it can be used as basic development platform of industry control, monitor, dada acquire, information analysis.
